2 Claims. (Cl. 222-566) The invention relates generally to metallic receptacles and primarily seeks to provide a novel plastic nozzle mounting on a metal can top or breast, and a novel method of preparing the mounting.

An object of the invention is to provide a nozzle mounting of the character stated which is neat in appearance, sturdy and liquid tight, and wherein the plastic nozzle is held securely against turning when a closure cap is threaded thereon.

Another object of the invention is to provide a nozzle mounting of the character stated wherein the plastic nozzle includes an externally threaded body, a flange projecting outwardly from the body, and a cylindrical base portion depending below the flange, and wherein the cap top or breast has a spout receiving seat comprising an inwardly directed horizontal fold of metal defining at its inward fold extremity a nozzle base receiving and impinging fold edge, the can breast or top metal extending above said fold being rolled over and embedded in the upper surface of the nozzle flange to securely clamp the nozzle in place.

A further object of the invention is to provide a novel method of preparing a nozzle mounting of the character stated wherein the breast isfirst provided with an upstanding cylindrical neck, then a lower portion of the neck is inwardly beaded, then the bead is flattened to form the inwardly directed nozzle flange receiving seat and provide a nozzle base receiving opening which has an inside diameter slightly less than the outside diameter of the cylindrical base of the nozzle, then the nozzle base is forced through said opening to seat the nozzle flange firmly on the seat with the inwardly directed opening defining fold formed by flattening the bead impinging the nozzle base, and then the remaining upstanding portion of the neck is turned inwardly over and onto the nozzle flange to secure the mounting of the nozzle.

A still further object of the invention is to provide a method of the character stated wherein in the inward turning of the remaining upstanding portion of the neck over and onto the nozzle flange the edge extremity of said neck portion is embedded in the flange so that no raw metal edge is exposed.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a fragmentary vertical cross section through the top portion of a can structure embodying the improved plastic nozzle mounting.

Figure 2 is a detail view illustrating the nozzle partly in side elevation and partly in vertical cross section.

Figure 3 is a sectional view illustrating the nozzle receiving neck as it is first drawn.

Figure 4 is a view similar to Figure 3 showing the neck after the inward beading thereof.

Figure 5 is a view similar to Figure 4 after the flattening or inward folding of the bead.

Figure 6 is a view similar to Figure 5 after the insertion of the nozzle base. t I

Figure 7 is an enlarged fragmentary sectional view showing the mounting completed by the infolding and embedding of the neck edge. a

In the example of embodiment of the invention herein disclosed, the improved nozzle mounting is incorporated in a container structure including a body 5 having a top. or breast 6 secured thereon by a conventional double seamv 7. The nozzle to be mounted preferably is molded from:

a deformable, resilient plastic, such as polyethylene, to include a tubular body 8 externally threaded at 9 and having an outwardly directed mounting flange 10 and a cylindrical base portion 11 depending below the flange in the manner clearly illustrated in Figure 2.

The container top is initially provided with an upstanding neck 12 providing an opening in which to receive the nozzle, and a lower portion of the neck is inwardly beaded at 13 in the process of forming the mounting, as indicated in Figure 4. The bead 13 is thereafter flattened to providea flat annular seat 14 comprising a double thickness fold, the inwardly directed extremity of which defines a circular opening 15 in which to receive the nozzle base portion 11.

The plastic nozzle and the receiving seat structure are so proportioned that the outside diameter of the nozzle base portion 11 is slightly larger than the inside diameter of the receiving opening 15 in the seat, and in the mounting of the nozzle the neck portion 11 is forced through the opening 15 to place the flange 10 firmly against the seat 14 and cause the inwardly directed seat fold extremity to be embedded in the base portion of the nozzle as at 16 in order to assure the provision of a liquid tight seal.

The remaining portion of the neck upstandingabove the nozzle flange 10 as at 17 is then turned inwardly over the flange as at 18 to firmly secure the flange in liquid sealing contact with the seat 14, said inwardly turned portion being embedded or indented in the plastic nozzle structure as at 19 to assure against presentation of raw metal edge portions.

The neck portion in which the plastic spout receiving seat is formed being formed integrally with the container top or breast 6, the fold providing the seat 14 being di rected inwardly and the outer edge extremity of the neck being turned inwardly and embedded in the plastic nozzle structure, no raw metal edge portions are presented interiorly or exteriorly of the container structure at the location of the nozzle mounting.

While one form of the invention has been shown for purposes of illustration it is to be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:

1. In a container structure, a deformable and resilient plastic nozzle comprising a tubular body including a mounting flange projecting outwardly therefrom and a cylindrical base portion depending below the flange, said flange having a fiat and horizontally disposed lower face and an outwardly and downwardly sloping upper face, and a metal mounting wall including an upright cylindrical portion at its lower extremity and an inwardly directed annular seat spaced above said extremity and directly engaged by the lower face of the nozzle flange and comprising a horizontal double thickness fold of the mounting wall metal with the two thicknesses in face to face contact one with the other and the inwardly directed fold extremity defining a circular opening receivinwardly over said flange with itswraw edge embedded in the flange to hold the flangeunder compression in vliquid sealtcontactuwith the seataand assure against exposure ofraw metal edgetportions, and the thickness of metal of the seat fold adjacent said lower extremity being connected with said cylindrical wall portion.

12. The herein described method of'providing a mounting for a deformable and resilient plastic nozzle having a tubular .body, a mounting flange projecting outwardly lfromt the body and a cylindrical base portion depending below the flange; said method comprising, providing a metal container wall with an upright cylindrical neck having an opening in which to receive the nozzle, forming an inwardlydirected bead in the neck and spaced above the lower extremity thereof, flattening the head to provide an annular seat onwhich to directly receive the nozzle flange, forming an inwardly directed fiat and horizontal double thickness fold of metal with the inwardly directed fold extremity defining a circular nozzle base portion receiving opening which has an inside diameter slightly less than the outside diameter of said base portion,'forcing the nozzle base portion through the receiving opening defined by said double thickness fold to firmly seat the flange of the nozzle directly on the annular seat and cause the inwardly directed receiving opening defining fold extremity to deform said base portion and be embedded in the nozzle base portion immediately below the nozzle flange, turning that portion of the neck extending endwise above the flange over and against the flange to secure the flange firmly against the seat and embedding the raw edge of the metal turned over the flange into the deformable and resilient flange so that the resilience of the plastic of the nozzle will overcome any tendency toward permanent deformation and loosening of the mounting due to relative movement of the flange and said raw edge and also to assure permanent- 1y against exposure of raw metal edge portions.
